One of my main gripes with DW when it was released was the lack of soft data on the sociology of Deathwatch Astartes. This problem still persists but on the other hand it also brings creative freedom with it.
One thing that seperates DW from common Special Forces RPGs is that the Astartes are Space Paladins steeped in millenia old traditions and rituals and we have the freedom to make up some of them on our own since FFG hasn't delivered (yet). Now we know a bit about the indiction into the DW (with painting the armour black and all) as that was described a bit in the rulebook. What we don't know about is the rituals of laying down your guns, saying farewell and the reception at home.
Now what I imagine is that you can't just remove only the outer black paint layer. The way I imagine it is that the marine's armour is getting stripped to its core (except for the chapter symbols and honours and campaign markings, etc.) and then polished. That might make the marine look a bit like Grey Knight though while he gets transferred home (where he would await his armour getting painted a new?). Still that could represent purity and leaving the life as a Deathwatch marine behind. Or of course he could get some appropriate (chapter dependent) primer sprayed on. Or he could get directly a new painting but that would be boring imho.
Any ideas for rituals and traditions surrounding the relief from Vigil?

Yes, traditions will be very different. However that didn't stop FFG from putting some paragraphs about induction into the rulebook. But mustering out is also interesting, especially since a player of mine is going to retire his PC.
